by instability do you mean it feels rough or shakes? possibly sounds like misfires within the engine? i am sure more experienced members can help u out if that is the case.

What engine do you have?

X5 4.4i E53 N62

It sounds like you have a missfire. When you rev the engine in N does it sound rough or nice a smooth as it should be?

no missfire, tremors, 'n' feels very little, 'D' more.

MAF maybe?
